 5.9    Currency; Exchange Rate. All payments to be made by
Licensee to Licensor under this Agreement shall be made in Dollars by bank wire transfer in immediately available funds to a bank account designated by written notice from Licensor. The rate of exchange to be used in computing the amount of currency
equivalent in Dollars shall be made at the average of the closing exchange rates reported in The Wall Street Journal (U.S., Eastern Edition) for the first, middle, and last business days of the applicable reporting period for the payment due.

 5.10    Blocked Currency. If the conversion of a local currency in the Territory into Dollars or
transfer of funds out of a country in the Territory becomes materially restricted, forbidden, or substantially delayed due to applicable Laws, then Licensee shall promptly notify Licensor and amounts accrued in such country may be paid by Licensee
in local currency into an account in a local bank designated by Licensor, unless the Parties otherwise agree. 

5.11    Late Payments. If Licensor does not receive payment of any sum due to it on or before the due date
therefor, simple interest shall thereafter accrue on the sum due from the due date until the date of payment at a per-annum rate of prime (as reported in The Wall Street Journal (U.S., Eastern Edition))
plus [***] or the maximum rate allowable by [***]. 
 5.12    Taxes. 

(a)    Taxes on Income. Each Party shall be solely responsible for all income taxes imposed on payments
received from the other Party under this Agreement. 
 (b)    Indirect Taxes. All payments in this
Article 5 are exclusive of indirect taxes (such as value added tax, sales tax, consumption tax and other similar taxes (“Indirect Taxes”)). The Parties shall cooperate in accordance with applicable Law to minimize Indirect Taxes in
connection with this Agreement. 
 (c)    Withholding and Tax Cooperation. Each Party will make all
payments to the other Party under this Agreement without deduction or withholding for taxes except to the extent that such withholding is required by applicable Law at the time of payment. The Parties agree to cooperate with one another and use
reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of all payments made under this Agreement to the fullest extent permitted by applicable Laws. To the extent Licensee is required to deduct and withhold taxes on
any payment to Licensor under applicable Law, Licensee shall deduct those taxes from the remittable payment, pay the taxes to the proper tax authority in a timely manner, and promptly send proof of payment to Licensor. To the extent permitted by
Law, Licensor shall provide Licensee any tax forms that may be reasonably necessary in order for Licensee to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Licensor shall use reasonable efforts
to provide any such tax forms to Licensee in advance of the due date. At the request and expense of Licensor, Licensee shall provide reasonable assistance to enable the recovery, to the extent permitted by Law, of withholding taxes or similar
obligations resulting from payments made under this Agreement. Notwithstanding anything to the contrary in this Agreement, in the event a Party redomiciles, assigns its rights or obligations under this Agreement, or otherwise makes payments from a
jurisdiction other than the jurisdiction in which such Party is organized (each, a “Tax Action” and such Party, the “Acting Party”), and as a result of such Tax Action the amount of tax required to be withheld under
this Section 5.12(c) in respect of a payment owed to the other Party (the “Non-Acting Party”) is greater than the amount of such tax that


  
 15 












 
would have been required to have been withheld had such Tax Action not occurred, then any such amount payable to or by the Non-Acting Party shall be
adjusted to take into account such withholding taxes or Indirect Taxes as may be necessary so that, after making all required withholdings (including withholdings on the additional amounts payable), the
Non-Acting Party receives an amount equal to the sum it would have received had such Tax Action not occurred. The obligation to adjust payments pursuant to the preceding sentence shall not apply, however, to
the extent such increased withholding tax (i) would not have been imposed but for a Tax Action taken by the Non-Acting Party if such Tax Action occurs after the Tax Action taken by the original Acting
Party referenced in the preceding sentence or (ii) is attributable to the failure by the Non-Acting Party to comply with the requirements of this Section 5.12(c). For purposes of this
Section 5.12(c), a “redomiciliation” shall include a reincorporation or other action resulting in a change in tax residence of the applicable Party or its assignee. 

5.13    Financial Records and Audit. Licensee shall maintain complete and accurate records in sufficient
detail to permit Licensor to confirm the accuracy of Net Sales and Sublicense Revenue reported by Licensee and the achievement of sales milestones under this Agreement. Upon at least [***] days’ written notice, such records shall be open for
examination, during regular business hours, for a period of [***] years from the creation of individual records by an independent certified public accountant selected by Licensor and reasonably acceptable to Licensee, for the sole purpose of
verifying for Licensor the accuracy of the financial reports provided by Licensee under this Agreement. Such audits shall be limited to once each Calendar Year and once with respect to records covering any specific period of time. Licensor shall
bear the cost of such audit unless such audit reveals an underpayment by Licensee of more than [***] percent ([***]%) of the amount actually due for the time period being audited, in which case Licensee shall reimburse Licensor for the costs of such
audit. Licensee shall pay to Licensor any underpayment discovered by such audit within [***] days after the accountant’s report, plus interest (as set forth in Section 5.11) from the original due date. If the audit reveals an overpayment
by Licensee, then Licensee may take a credit for such overpayment against any future payments due to Licensor (if there will be no future payment due, then Licensor shall promptly refund such amount to Licensee). 

ARTICLE 6 
 INTELLECTUAL
PROPERTY RIGHTS 
 6.1    Inventions. Ownership of all Inventions shall be based on inventorship, as
determined in accordance with the rules of inventorship under United States patent laws. Each Party shall solely own all Inventions invented or developed solely by or on behalf of such Party, including its and its Affiliate’s employees,
contractors, and/or agents, and all intellectual property rights therein. The Parties shall jointly own all Inventions invented or developed jointly by both Parties and all intellectual property rights therein (“Joint Inventions”).
All Patent Rights claiming Joint Inventions will be referred to as “Joint Patents”. Except to the extent restricted by the licenses and other rights granted to other Party under this Agreement or any other agreement between the
Parties, each Party, as joint owners, shall be entitled to practice, license, assign, and otherwise exploit its interest in the Joint Inventions and to grant rights to others to practice such Joint Inventions, without the duty of accounting or
requirement to seek consent from the other Party.

 6.2    Patent Prosecution. 

(a)    As between the Parties, Licensee shall have the first right to file, prosecute, and maintain the Licensed
Patents that specifically claim inventions directed to the Compound or Products (including for clarity any Joint Patents which are Licensed Patents) in the Territory (“Product-Specific Licensed Patents”), at Licensee’s cost and
expense. As of the Effective Date, the Product-Specific Licensed Patents are expressly designated as such on Exhibit B. Promptly after the Effective Date, Licensor shall transfer the prosecution and maintenance of the Product-Specific
Licensed Patents to Licensee or its counsel. As between the Parties, Licensor shall have first right to file, prosecute, and maintain the Licensed Patents (including for clarity any Joint Patents which are Licensed Patents) that are not
Product-Specific Licensed Patents (“Non-Product-Specific Licensed Patents”) in the Territory at Licensor’s cost and expense. 

(b)    Licensee shall consult with Licensor and keep Licensor reasonably informed of the status of the
Product-Specific Licensed Patents and shall promptly provide Licensor with a copy of any material correspondence received from any patent authority in the Territory in connection therewith. In addition, Licensee shall provide Licensor with drafts of
proposed material filings and correspondence to any patent authority in the Territory with respect to the Product-Specific Licensed Patents for Licensor’s review and comment at least [***] business days prior to the anticipated submission date
or due date (whichever is earlier), and Licensee shall reasonably consider all comments provided to Licensee by Licensor within [***] business days of Licensor receiving such draft. 

(c)    Licensee shall notify Licensor of any decision to cease prosecution or maintenance of any Product-Specific
Licensed Patents in any country in the Territory. Licensee shall provide such notice at least [***] days prior to any filing or payment due date, or any other due date that requires action, in connection with such Product-Specific Licensed Patent.
In such event, upon Licensor’s request, Licensee shall transfer all files and documents in Licensee’s possession and Control necessary for the prosecution and maintenance of such Product-Specific Licensed Patent in such country to
Licensor, and thereafter Licensor shall have the right to continue prosecution or maintenance of such Product-Specific Licensed Patent in such country at Licensor’s cost and expense. Licensor shall notify Licensee of any decision to cease
prosecution or maintenance of any Licensed Patents that is not a Product-Specific Licensed Patent in any country in the Territory. Licensor shall provide such notice at least [***] days prior to any filing or payment due date, or any other due date
that requires action, in connection with such Licensed Patent. In such event, upon Licensee’s request, Licensor shall transfer all files and documents in Licensor’s possession and Control necessary for the prosecution and maintenance of
such Licensed Patent in such country to Licensee, and thereafter Licensee shall have the right to continue prosecution or maintenance of such Licensed Patent in such country at Licensee’s cost and expense. 

(d)    Section 6.2(b) above shall apply mutatis mutandis as if Licensee were Licensor and as if Licensor
were Licensee with respect to the prosecution and maintenance of the Non-Product-Specific Licensed Patents. 

  
 17 












 (e)    The Parties shall mutually agree on which Party will
prosecute Joint Patents which are not Licensed Patents based on the contribution of each Party to such Joint Invention and each Party’s potential interest in products based upon such Joint Invention. 

(f)    Each Party shall provide the other Party all reasonable assistance and cooperation in the patent
prosecution efforts under this Section 6.2, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution. 

6.3    Patent Enforcement. 

(a)    Notice. Each Party shall promptly notify the other Party if it becomes aware of any alleged or
threatened infringement by a Third Party of any Licensed Patent (including any Joint Patents which are Licensed Patents) arising by the manufacture, use, import, or sale of a Product in the Field in the Territory (the “Field
Infringement”). 
 (b)    Enforcement. [***]. 

(c)    Cooperation. [***]. 

(d)    Recovery. [***]. 

6.4    Defense of Licensed Patents. In the event that a Party receives notice of any claim alleging the
invalidity or unenforceability of any Licensed Patent, such Party shall bring such claim to the attention of the other Party, including all relevant information related to such claim. The Parties, through the JSC, shall discuss such claim. Where
such allegation is made in an opposition, reexamination, interference, or other patent office proceeding or a declaratory judgement action, then the provisions of Section 6.2 shall apply to determine the Parties’ respective rights and
obligations with respect to such allegation; provided however that if a Party wishes to bring an infringement claim to enforce the Licensed Patent, then the provisions of Section 6.3 shall apply to determine the Parties’ respective rights
and obligations with respect to such allegation. 
 Each Party shall provide to the Party defending any such rights under this
Section 6.4 all reasonable assistance in such enforcement, at such defending Party’s request and expense. The defending Party shall keep the other Party reasonably informed of the status and progress of such efforts, and shall reasonably
consider the other Party’s comments on any such efforts. Without the prior written consent of the other Party (not to be unreasonably withheld), neither Party shall enter into any settlement of any claim, suit, or action that it defended under
this Section 6.4 that admits the invalidity or unenforceability of any Licensed Patent or otherwise adversely impacts the other Party’s interest therein. 

6.5    Defense of Third Party Claims. If a claim is brought by a Third Party alleging infringement of a
Patent Right of such Third Party by the Development, manufacture, or Commercialization of the Product, the Party first having notice of the claim or assertion shall promptly notify the other Party, [***].

 6.6    Bankruptcy Protection. All licenses granted by
Licensor to Licensee under this Agreement are and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11, United States Code or foreign equivalent laws (the “Bankruptcy Code”), licenses of rights to
“intellectual property” as defined in Section 101 of the Bankruptcy Code. Licensee shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code. Upon the bankruptcy of Licensor, Licensee shall further
be entitled to a complete duplicate of, or complete access to, any such intellectual property, and such, if not already in its possession, shall be promptly delivered to Licensee, unless Licensor elects to continue, and continues, to perform all of
its obligations under this Agreement. 
 ARTICLE 7

7.1    Confidentiality Obligations. Except to the extent expressly authorized by this Agreement or otherwise
agreed in writing by the Parties, each Party agrees that, during the Term of this Agreement and ten (10) years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as

Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or
available to the general public or in the rightful possession of the receiving Party unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the receiving Party. 

7.3    Authorized Disclosures. Notwithstanding the obligations set forth in Sections 7.1 and 7.5, a Party
may disclose the other Party’s Confidential Information to the extent:

other financial or business partners for the purpose of evaluating or carrying out an actual or potential investment, acquisition, collaboration, or other business relationship; provided that in each such case on the condition that such recipients
are bound by confidentiality and non-use obligations substantially consistent with those contained in this Agreement prior to such disclosure; 

(c)    such disclosure is required by applicable Laws or judicial or administrative process (including regulations
promulgated by securities exchanges), provided that in such event such Party shall promptly inform the other Party of such required disclosure and provide the other Party an opportunity to challenge or limit the disclosure obligations. Confidential
Information that is disclosed pursuant to this Section 7.3(c) shall remain otherwise subject to the confidentiality and non-use provisions of this Article 7, and the Party disclosing Confidential
Information pursuant to Law or court order shall take steps reasonably necessary, including seeking to obtain confidential treatment or a protective order, to ensure the continued confidential treatment of such Confidential Information. 

7.4    Technical Publication. Licensee shall have the sole right, in its discretion, to publish or otherwise
disclose the results of and other information regarding any Development activities performed under this Agreement by or on behalf of Licensee with respect to the Compound and Product. Licensor shall not publish or otherwise disclose any information
regarding the Compound or Product without Licensee’s prior written consent (not to be unreasonably withheld, delayed, or conditioned), to be given on a case-by-case
basis. 
 7.5    Publicity. 

(a)    The Parties have agreed on language of a joint press release announcing this Agreement, which is attached

Party shall be free to disclose or publicize, without the other Party’s prior written consent, the existence of this Agreement, the identity of the other Party, and those terms of the Agreement which have already been publicly disclosed in
accordance herewith. 

  
 20 












 (b)    A Party may disclose this Agreement and its terms in
securities filings with the Securities Exchange Commission or other Government Authorities to the extent, in the opinion of the disclosing Party’s counsel, is required by Law or rules of a securities exchange after complying with the procedure
set forth in this Section 7.5. In such event, the Party seeking such disclosure will provide a copy of the proposed disclosure to the other Party, and the other Party agrees to promptly (and in any event, no less than seven (7) days after
receipt of such proposed disclosure) give its input in a reasonable manner in order to allow the Party seeking disclosure to make such required disclosure within the time lines proscribed by applicable Laws or rules of a securities exchange. 

(c)    Each Party acknowledges that the other Party may be legally required to make public disclosures (including
in filings with the Securities Exchange Commission) of certain material developments or material information generated under this Agreement and agrees that each Party may make such disclosures as required by Law or rules of a securities exchange.

 7.6    Prior CDA. [***]. 

7.7    Equitable Relief. Each Party acknowledges that a breach of this Article 7 may not reasonably or
adequately be compensated in damages in an action at law and that such a breach may cause the other Party irreparable injury and damage. Therefore each Party agrees that the other Party shall be entitled, in addition to any other remedies it may

ARTICLE 9 

INDEMNIFICATION; LIABILITY 

9.1    Indemnification by Licensor. Licensor shall indemnify and hold Licensee, its Affiliates, Sublicensees,
and their respective officers, directors, agents and employees (“Licensee Indemnitees”) harmless from and against any Claims against them to the extent arising or resulting from: 

(a)    the negligence or willful misconduct or breach of this Agreement by any of the Licensor Indemnitees; 

  
 23 












 (b)    Licensor’s breach of this Agreement, including any
representation or warranty made by Licensor hereunder; or 
 (c)    the Development or manufacture of the
Compound and Product by or on behalf of Licensor or its Affiliates before the Effective Date; 
 except in each case to the extent such Claims result
from any activities set forth in Section 9.2 for which Licensee is obligated to indemnify the Licensor Indemnitee. 

9.2    Indemnification by Licensee. Licensee shall indemnify and hold Licensor, its Affiliates, and their
respective officers, directors, agents and employees (“Licensor Indemnitees”) harmless from and against any Claims against them to the extent arising or resulting from: 

(a)    the negligence or willful misconduct or breach of this Agreement by any of the Licensee Indemnitees; 

(b)    Licensee’s breach of this Agreement, including any representation or warranty made by Licensee
hereunder; or 
 (c)    the Development, manufacture, or Commercialization of the Compound and Product by or on
behalf of Licensee, its Affiliates, or Sublicensees; 
 except in each case, to the extent such Claims result from any activities set forth in
Section 9.1 for which Licensor is obligated to indemnify the Licensee Indemnitee. 

9.3    Indemnification Procedure. If either Party is seeking indemnification under Sections 9.1 or 9.2 (the
“Indemnified Party”), it shall inform the other Party (the “Indemnifying Party”) of the Claim giving rise to the obligation to indemnify pursuant to such Section as soon as reasonably practicable after receiving
notice of the Claim. The Indemnifying Party shall have the right to assume the defense of any such Claim for which it is obligated to indemnify the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party and the
Indemnifying Party’s insurer as the Indemnifying Party may reasonably request, and at the Indemnifying Party’s cost and expense. The Indemnified Party shall have the right to participate, at its own expense and with counsel of its choice,
in the defense of any Claim that has been assumed by the Indemnifying Party. Neither Party shall have the obligation to indemnify the other Party in connection with any settlement made without the Indemnifying Party’s written consent, which
consent shall not be unreasonably withheld or delayed. The Indemnifying Party may not settle any Claim without the prior written consent of the Indemnified Party, such consent shall not be unreasonably withheld or delayed, provided, however, that
the Indemnifying Party shall not be required to obtain such consent if the settlement: (a) involves only the payment of money and does not cause the Indemnified Party to be subject to injunctive or other similar type of relief; (b) does
not require an admission by the Indemnified Party; and (c) does not adversely affect the intellectual property Controlled by, or the rights or licenses granted to the Indemnifying Party (or its Affiliate) under this Agreement. If the Parties
cannot agree as to the application of Section 9.1 or 9.2 as to any Claim, pending resolution of the dispute pursuant to Section 11.6, the Parties may conduct separate defenses of such Claims, with each Party retaining the right to claim
indemnification from the other Party in accordance with Section 9.1 or 9.2 upon resolution of the underlying Claim. 

  
 24 












 9.4    Mitigation of Loss. Each Indemnified Party shall
take and shall procure that its Affiliates take all such reasonable steps and action as are reasonably necessary or as the Indemnifying Party may reasonably require in order to mitigate any Claims (or potential losses or damages) under this Article
9. Nothing in this Agreement shall or shall be deemed to relieve any Party of any common law or other duty to mitigate any losses incurred by it. 

9.5    Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL,
INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 9.5 IS INTENDED TO OR SHALL LIMIT
OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 9.1 OR 9.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 7. 

9.6    Insurance. Each Party, at its own expense, shall maintain commercial general liability insurance and
product liability and other appropriate insurance, in amounts consistent with sound business practice and reasonable in light of its obligations under this Agreement. Each Party shall maintain such insurance for the period [***]. Each Party shall
provide a certificate of insurance evidencing such coverage to the other Party upon request. It is understood that such insurance shall not be construed to create any limit of either Party’s obligations or liabilities with respect to its
indemnification obligations under this Agreement.

ARTICLE 11 
 GENERAL
PROVISIONS 
 11.1    Force Majeure. Neither Party shall be held liable to the other Party nor be
deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected
Party, including embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, earthquakes or other acts of God, or acts,
omissions or delays in acting by any governmental authority or the other Party. The affected Party shall notify the other Party in writing of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake and continue
diligently all reasonable efforts necessary to cure such force majeure circumstances or to perform its obligations in spite of the ongoing circumstances; provided that if the force majeure circumstances continue despite such efforts and


  
 27 












 
prevent the affected Party from performing its obligations hereunder for more than [***] days, the other Party may request that the Parties meet to discuss the anticipated duration of any further
delay and any amendments to this Agreement proposed by a Party in good faith in light of the anticipated duration of any further delay. 

11.2    Assignment. Except as expressly provided hereunder, neither this Agreement nor any rights or
obligations hereunder may be assigned or otherwise transferred by either Party without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned, or delayed); provided, however, that either Party may

permitted assigns of the Parties, and the name of a Party appearing herein will be deemed to include the name of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Section 11.2. Any
assignment not in accordance with this Section 11.2 shall be null and void and of no legal effect. 

11.3    Severability. If any one or more of the provisions contained in this Agreement is held invalid,
illegal, or unenforceable in any respect, the validity, legality, and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely
affects the substantive rights of the Parties. The Parties shall in such an instance negotiate in good faith to promptly replace the invalid, illegal, or unenforceable provision(s) with valid, legal, and enforceable provision(s) which, insofar as
practical, implement the original intent of the Parties.

 29 












 (d)    Arbitration. If the Senior Officers are not able
to agree on the resolution of a Dispute within [***] days (or such other period of time as mutually agreed by the Senior Officers) after such Dispute was first referred to them, then, except as otherwise set forth in subsection (c) above, if a
Party wishes to pursue further resolution of such Dispute, such Dispute shall be finally resolved by binding arbitration in accordance with this Section 11.6(d). Such Dispute shall be referred to and finally resolved by arbitration administered

may be entered in any court of competent jurisdiction. Except to the extent necessary to confirm, enforce, or challenge an award of the arbitration, to protect or pursue a legal right, or as otherwise required by applicable Law or regulation or
securities exchange, neither Party nor any arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of both Parties. Notwithstanding anything to the contrary in the foregoing, in no
event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy, or claim would be barred by the applicable Delaware statute of limitations. Any disputes concerning the
propriety of the commencement of the arbitration shall be finally settled by the arbitral tribunal. 

(e)    Interim Relief. Notwithstanding anything herein to the contrary, nothing in this Section 11.6
shall preclude either Party from seeking interim or provisional relief, including a temporary restraining order, preliminary injunction, or other interim equitable relief concerning a Dispute in any court of competent jurisdiction before or after
the initiation of an arbitration as set forth in Section 11.6(d), if necessary to protect the interests of such Party. This Section shall be specifically enforceable.

Joint Press Release 

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION AS DEFINED UNDER THE MARKET ABUSE REGULATION (EU) NO. 596/2014. UPON PUBLICATION OF THIS
ANNOUNCEMENT THIS INFORMATION IS NOW CONSIDERED IN THE PUBLIC DOMAIN. 
 Mereo BioPharma and Oncologie Enter into Global Licensing
Agreement for Navicixizumab 
 Oncologie receives exclusive global license to develop and commercialize navicixizumab 

London, Redwood City, Calif., and Boston, January 13, 2020 - Mereo BioPharma Group plc (NASDAQ: MREO, AIM: MPH),
“Mereo” or the “Company,” and Oncologie, Inc. (“Oncologie”) today announced a global license agreement (the “License Agreement”) for the development and commercialization of navicixizumab, an anti-DLL4/VEGF
bispecific antibody currently being evaluated in an ongoing Phase 1b study in combination with paclitaxel in patients with advanced heavily pretreated ovarian cancer. Navicixizumab previously completed a Phase 1a monotherapy study in patients with
various types of refractory solid tumors and is one of two product candidates Mereo acquired through its 2019 merger with OncoMed Pharmaceuticals, Inc. In October 2019, the U.S. Food and Drug Administration (“FDA”) granted Fast Track
designation to navicixizumab and has agreed in principle on the design of a study that could potentially support accelerated approval for navicixizumab in a heavily pretreated, platinum-resistant ovarian cancer patient population. 

Under the terms of the License Agreement, Oncologie will receive an exclusive worldwide license to develop and commercialize navicixizumab. Mereo will receive
an upfront payment of $4 million with an additional payment of $2 million conditional on a CMC (Chemistry, Manufacturing and Controls) milestone. Oncologie will be responsible for all future research, development and commercialization of
navicixizumab. Additionally, Mereo will be eligible to receive up to $300 million in future clinical, regulatory and commercial milestones, tiered royalties ranging from the mid-single-digit to sub-teen percentages on global annual net sales of navicixizumab, as well as a negotiated percentage of sublicensing revenues from certain sublicensees. 

“We believe Oncologie is expertly positioned to further advance navicixizumab through clinical development and towards potential commercialization,”
said Dr. Denise Scots-Knight, Chief Executive Officer of Mereo. “While we believe navicixizumab is an exciting oncology asset, we continue to focus our primary efforts on the development of our innovative rare disease portfolio including
our lead product candidate setrusumab for the treatment of osteogenesis imperfecta, which continues to advance towards a pivotal Phase 3 pediatric study.” 











 “We believe navicixizumab is a strong strategic fit with our portfolio of innovative oncology assets,
and we are excited to enter into this agreement with Mereo,” said Laura E. Benjamin, Ph.D., Chief Executive Officer of Oncologie. “Navicixizumab has demonstrated robust activity when combined with paclitaxel in a Phase 1b study in
platinum-resistant ovarian cancer patients including those who received prior bevacizumab. Navicixizumab has also demonstrated promising activity in a Phase 1b monotherapy study of heavily pretreated ovarian cancer patients, as well as in other
tumor types. We seek to leverage the strong development and regulatory progress Mereo has already made to continue its development and ultimately make this investigational therapy available to patients as quickly as possible.” 

As a consequence of the License Agreement with Oncologie, and in accordance with the terms and conditions of the Contingent Value Rights Agreement for former
stockholders of OncoMed Pharmaceuticals, Inc. (“OncoMed”), dated April 23, 2019, by and among Mereo and Computershare Inc., as rights agent, (the “Mereo CVR Agreement”), holders of contingent value rights
(“CVRs”) pursuant to the Mereo CVR Agreement will be entitled to receive certain eligible cash milestone payments made to Mereo under the License Agreement relating to navicixizumab. Details of the amount payable to holders of CVRs from
the upfront payment will be announced within thirty days of the effective date of the License Agreement. Pursuant to the terms of the Mereo CVR Agreement, if a milestone occurs prior to the fifth anniversary of the closing of Mereo’s merger
with OncoMed, then holders of CVRs will be entitled to receive an amount in cash equal to 70% of the aggregate principal amount received by Mereo after deduction of costs, charges and expenditures set out in detail in the Mereo CVR
Agreement. Such milestone payments are also subject to a cash consideration cap, pursuant to which the aggregate principal amount of all cash payments made to holders of CVRs under the Mereo CVR Agreement shall in no case exceed
$79.7 million. 
 About Navicixizumab 

Navicixizumab is an anti-DLL4/VEGF bispecific antibody designed to inhibit both Delta-like ligand 4 (“DLL4”) in the Notch cancer stem cell pathway as
well as vascular endothelial growth factor (“VEGF”) and thereby induce potent anti-tumor responses while mitigating certain angiogenic-related toxicities. In preclinical studies, navicixizumab demonstrated robust in vivo anti-tumor
activity across a range of solid tumor xenografts, including colon, ovarian, lung and pancreatic cancers, among others. In a Phase 1a study with single-agent navicixizumab, 19 of 66 patients with various types of refractory solid tumors had tumor
shrinkage following treatment with navicixizumab. Notably, 3 of the 12 (25%) ovarian cancer patients treated in the trial achieved an unconfirmed partial response with single-agent navicixizumab therapy. 

A Phase 1b dose escalation and expansion study of navicixizumab plus paclitaxel has completed enrollment of 44 platinum resistant ovarian cancer patients who
had failed >2 prior therapies and/or received prior bevacizumab. As of the last interim data analysis at the end of Q1 2019, the unconfirmed response rate was 41%. The unconfirmed ORR for
bevacizumab-naïve patients was 64% and 30% for bevacizumab pre-treated patients. The median PFS for all patients was 7.3 months. The most common related adverse
events of any 











 
grade were hypertension (68%), fatigue (46%), headache (25%), neutropenia (21%), diarrhea (18%), pulmonary hypertension (14%), dyspnea (14%) and peripheral edema (14%). Other related adverse
events of special interest were one Grade 1 related heart failure, one Grade 3 and one Grade 4 related thrombocytopenia, and one Grade 4 related gastrointestinal perforation. 

The FDA has granted Fast Track designation to navicixizumab for the treatment of high grade ovarian, primary peritoneal or fallopian tube cancer in patients
who have received at least 3 prior therapies and/or prior bevacizumab. Following a Type B End of Phase 1 meeting with the FDA held in July 2019, the FDA agreed in principle on an outline for a Phase 2 clinical trial that could potentially support
accelerated approval of navicixizumab in this ovarian cancer patient population.
